mating old and new drywall
#1

In the process of removing a hall closet and adding a bedroom closet, I have removed and added some framing. I now have a couple of sections where I have new drywall meeting existing drywall (that has a few coats of paint). This occurs along inside corners as well as butted joints.
My question is how do I join the two? Just treat like a normal taping job with all new drywall? How is the bond of joint compound to paint?
Thanks for your suggestions and comments.
